To all 'wjwm, it may 001mm.-

Be it known that I, WILLI M W. HUNT, a citizen of the United States, residing-at Bexle in the. county of Franklin and State of 0 io, have invented a certain new and uselowing is a specification.

Rubber heels have been made either as whole heelsor half heels. Whole heels are manufactured with the base lift or base of leather or hard rubber for attachmentdirectly' to the primary sole. .The soft vrubber half heels, especial y the half heels for repair or replaoemen jobs are commonly provided with nail sto s 1n the form of small metallic rings embe ded at the proper points involveda high cost in the matter of time and money because of the necessity of plac-' ing each one on a pin in the bottom of the heel mold. 1 v H The objectof the present invention is more especially to provide a whole heel in which .the nail. stop is formed by pro'ecting the hard rubber or rubber compoun base lift at the necessary points and to the desired. distance into the'soft rubber top lift.

A further object is toefl'ect a more intimate and ti liter relation between the topnmd base li Other objectsmay be gathered from the following descript on.

The invention is embodied in the example herein shown and deggribed the features of novelty being finally claimed.

In the accompanying drawin Figure 1 is atop plan view 0 the heel is prepared for the. inanufacturen- Fig. 2 is a section on the line II-I'I Fi 1. o. r ig. 4 is a plan view of the bottom or In the views 5 designates the top or soft rubber lift said lift being molded with nail holes 6. The character '7 designates the base 7 Heels, of which the'folhave ed base or l and suitable plastic material said lift having conical extensions 8 reachin to the top of the nail holes 6. The base lift is provided with several openings 9 into which the soft rubber flows in the molding operation.

Inmanufacturing such a heel the bottom plate contains the pins for forming the nail holes, the middle member form's-the edge of the soft rubber'part while the top memoer forms or receives the outer rim of thebase lift. The bottom or soft portion is first put into the mold in the rough and then the hard portion which is shaped and prepared in advance is placed upon the soft portion and pressure applied during the vulcanizing process. The conical portions of the base lift? penetrates the soft portion and the-overflow oozes u into the'openings 9 thus effecting a keye and close union between the two lifts subpplementing the vulcanizing union. The reast of the heel is formed so as lift of hard rubber composition or other a to require no trimming but the base lift This process ermits a neat finishingof the heel and the o literation of anyline of division between the-hard and soft lifts.

The forms of the parts can be changed and the-process varied without departing from th'e gist' of the invention as claimed. What I claim is:

1. A heel comprising, in combination, a
